Application filed January 20, 19M. Serial No. 813,163.

To all whom it may concern:

Be it known that I. Gnovnn F. CovenonLL, e. citizen of the UnitedStates, residing in Council Bluli's, in the county of lottewattamie andState of Iowa, have invented cer-- tain 11B and useful improvements inType Writing lyiacliines of which the followieg is e specification.

This invention relates to a. feeding device for typewriting machines,whereby envelops cerds and paper sheets can be sue-oessively fed to theplaten roll of the machine by merely turning such roll.

The invention has for one of its objects to improve. and simplify theconstruction and operation of devices of this character so es to becomparatively simple and inex pensive to nienofzicture, reliable endeificient in use, and readily manipulated and adapted for use on anystandard typewriter. Y

Another object of the invention is the different sizes of envelope,cords and paper. Still another object oi the invention is the employmentof an improved 0 crating connection between the platen vol of thetypewriter andthe feed rollers of the ettachment.

A further feature of the invention is the provision of adjustable guidesto receive the envelop or sheet, as it emerges from the platen, to guideit clear of the magazine.

With these objects in view, and others as will appear as the descriptionprooeeds, the invention comprises the various novel features ofconstruction and arrangement of .perts which will be more fullydescribed hereinafter and set forth with p. "ticularity' in the claimsappended hereto.

In the accompanying drawings, Figure 1 I is a front view of thisinvention detached from the typewriter. Fig. 2 is a rear view of thesame, showing the feed rolls and their driving mechanism. sectionalelevation of the some mounted over a platen frame, which is showndiagrammatically. Fig. 4 is a perspective view of oneof the guide 6 gas.Fig. 5 is a perspective View of 1' sections of the ;:-:.per or envelopholder.

Fig. '6 is a fragmentary perspective view of one end of the bottomsection of the holder. Fig. 7 is a fragmentary perspective View of Fig.3 is a. side.

Similar reference characters are employed to designate correspondingparts throughout the Several views.

Referring to the drawing, A designates the bottom section of the rack orholder for the envelope, paper or cards, and'mounted on this bottomsection are adjustable end sections B, whereby tlie'rack can be widened10.1" shortened according to the size of the paper, envelope or cords tobe typewritten. The bottom section A is composed of two guide plates orbars 1 and 2 which are spaced apart to provide a guide passage 3,

through which the paper or envelops are fed, and seemed to the ends ofthese plates or bars are brackets e, serving to secure the attachmentto-the carriages? of the typewriter, these brackets being of any desiredshape or design'=to suit different makes of tybewritingmachines. Thefront guide plate l-is bent io'i werdly into a. horizontally attendingplate portion 5, which has its ont edgejbent. upwardly into a. flange 6extending full length of the bottom section, thereby stifiening thestructure and forming a shallow chamber *8 with the receiving regulatorplate '8. The rear plate 2- pro ject's above. the horizontal pleteportion 5 to serve to holdthe rearmost sheet of paper,

' envelop or the like in line with the'feed or 10 engage the end edgesof the sheets or euveloos to hold them all in even pile and on eacmember 10 is an inwardly extending finger l3 spaced from the portions 11to hold the sheets or enveloys in upright position and preventing themfrom tilting forwardly. On the bottom of eaeh member 10 is e footextension le which rests on the horizontal plate '5 of the bottomseetionA. Each extension 11,.as shown inl ig. 5, has an inverted U-shaped lugthat has a slid ing engagement with the flange 6 of the bottom sectionof the rack or holder and the outer frontportionot' the lug has? adepending linger piece 16, whereby the end the end sections are securelyheld on the 'bottom section, although free to slide in wardly oroutwardly to change the width of the holderor rack, 1 I

The envelope orsheets are fed from the raclrhy means of spaced rubberfaced rollersfil mounted on a rotary shaft 22 disposed behind the bottomsection of the rack and journaledin'hearings fi secured to the ends ofthe hot-tom section A and the fore ward portions of the rollers extendthrough openings in the back plate 52 of the hottom section. 9n one endof the shaft supported a framed?) composed oispaced platesbetween whichare mounted gear wheels, whereby motion can be transmitted to the shaft22 by the platen roll 22. A. large year wheel. 26 is'journaled in theframe and has a hollow hub 27 through which the platen shaft :27extends, the hub being rigidly secured to the shaft in any suitablemanner. The shaft passes through the frame and l12lS=Zl pinion :28,which is' driven from the gear 26, by means of intermediate gears'29. Itwill be obvious-that the turning of the platen will result in theautomatic. feed of one sheet or envelop at a time vfrom the attachmentto the platen. Cooperating with each feed roller 21 is gripping roller31 mounted on the front bar or plate 1 of thebotton'i section infrictional engagement with its companion-feed roller 21. Thefrictionrollers 31 are arranged under the horizontal plate portion 5ofthe bottom section 'A and they engage their re spective feed rollersthrough openings 32 (Fig. 6), in the bar or plate 1. lrlounted on thebottom section of the holder or rack is a regulator plate 33,.which hasits rear edge 34' disposed adjacent the feed rollers, where they projectthrough the openings;

andthis regulator plate is adjustable toward forfrom the rollersaccording ness of theenvelop,xpaper.or card, so that butonesheet,envelop or card dill feed at! 'a time. This plate 33 is disposed overthe to the. thickforward horizontal projecting portion f the bottomsection and has-itsior rard edge bent downwardly into a longitudinalflange- 'ing feedand friction rollers of 35, which is disposed in frontof the flange 6 and is secured to the same by bolts 36. On these boltsare resilient washers 37 or equivalent devices, so that by tightening orloosening the nuts of the bolts the rear edge of the regulator plate canbe adjusted with respect to the feed rollers. -The top surface. of theregulator plate shown in F i'g. 7, is inclined downwardly and rearwardlyso thatthe lower edges of envelops' or sheets will. rest on thisinclined portion of the pile and thereby the pile will be formed into acomb. The edge 34 of theregulator plate is disposed approximately in ahori- Ii'ontal plane passing through the axis of the feed rollers andimmediately under this edge 3- are located the friction rollers 31 .sothat the said friction rollers will take hold of the rear-most card,envelo a, or sheet as the latter is moved downwardly off the. regulatorplate by the feed rollers.

In practice, it -"hasgoeen found that the regulator plate for envelopeshould be constructed as shown in Fig. '1, with the marginal portion 34slightly convexed at its top surface, while the regulator plate, (Fig.8), for paper sheets should have itsrear marginalportionslightly-"concave so as tobe disposed more nearly in a radialposition with respect to thefeed rollers. To insure the proper feedingin of the workieces, an arcuate wire 38 is attached at eac end to thebolts 36, and bent rearwardly against said work-pieces, to constantlyurge the latteronward to-the bite of the feed rolls 21 and 31; As thetop edge of the work-piece moves away from the platen, after receivingsuccessive lines of impressions from type 39, I

its side edges are engaged by fingers 40 and guided clear. of themagazine through channels 41, formed by heading back portions 42 of theI said fingers, as shown in Fig: {1. These fingers are shiftablysupported at 4:3 or? the flange 6 of the front guide plate 1,

"and may'he adjusted for variations in the width ol'th, work-pieces.

. In operation, theend sections are adjusted inwardly or outwardlyaccording to the width of the envelope, cards of sheets to betypewritten and a proper regulator plate is placed on the bottom sectionand adjusted hack and forth into operative relation with the feedrollers. A pile of envelops, cards, 0:: sheets, as the case may be, isplaced in the holder or rack in an approximately vertical position, theends of the pile being held by the end sections B, while the bottom ofthe pile rests-on the'regulator plate with the rearmost envelop, card,or sheet The. platen the co-actthe attachmentto removethe' rearmostenvelop, cardor shee tand bring it into cooperative relatioi'r. with thefeeding mechanism of the" in contact with the feed rollers. rollislnowturned so as to cause claim:
